Household Electric Circuits The standard U.S. household wiring design has two 120 volt "hot" wires and a neutral which is at ground potential. The two 120 volt wires are obtained by grounding the centertap of the transformer supplying the house so that when one hot wire is swinging positive with respect to ground, the other is swinging negative.

Ground Rules for Household Wiring When it comes to upgrading or repairing household wiring and electrical systems, homeowners usually call a licensed professional to do the work. But whether you own your home or rent an apartment, bringing the wiring in your residence up to the current National Electrical Code could enhance your safety—every time you flip a switch or plug into an outlet.

How to Install Electrical Wiring Use these tips and instructions for adding new electrical wiring. Take a few minutes to read the directions thoroughly. Following these instructions can save you time and effort and ensure a safe installation.

Howstuffworks "Rough Electrical" The purpose of the electrical system in a house is to distribute the power safely to all of the different rooms and appliances.

How Power Distribution Grids Work goes into extensive detail on how power gets from the power plant to your house.

Electrical Intro A textbook intended for trainees in the field of electrical engineering. It is also suitable for electricians who want to make themselves again acquainted with the theoretical fundamentals of electrical engineering by private study and qualify for higher positions.

Electrical Installation This textbook “Fundamentals of Trade - Electrical Installation” concerns all trainees working as electrical fitters or service electricians in vocations of power installation. It contains a choice of the most important installation technologies resp. techniques to be mastered in the wide working field of installing electrical plants up to 1 kV. A multiple of illustrations assists in understanding the text. In particular these illustrations serve for easy classification and systematizing of the individual installation activities.

Electric Circuits This Textbook is intended for all trainees in the field of electro-technology. It contains the more important circuit diagrams and formulas and a limited number of selected tables of direct-current and alternating-current engineering. With the help of this Textbook, the trainee will be in a position to read and interpret electrical wiring and circuit diagrams in order to perform his job according to the rules of good workmanship. At the same time, the trainee is encouraged to prepare and draw circuit diagrams without assistance and to use graphical symbols correctly.

Electrical Cables Handling and Connection of Cables and Lines for Fixed Laying - Course: Basic skills and knowledge of electrical engineering. Trainees' handbook of lessons (Institut für Berufliche Entwicklung, 17 p.) contains a description of the operations and tools required for the handling and connection of cables and lines for fixed laying. The methods required are explained in self-contained sections. The necessary knowledge and skills are described in each section in the order of the steps of work required. The illustrations contained shall help to visualize, understand and supplement the text of the individual sections. To assist the learning process, questions have been included for the trainees to test their knowledge.

Electrical Lines Treatment of Lines for Mobile Devices and Appliances - Course: Basic skills and knowledge of electrical engineering. Trainees' handbook of lessons (Institut für Berufliche Entwicklung, 21 p.) describes the operations and auxiliary means required for the treatment of lines for mobile devices and appliances. The required methods are explained in individual sections. The required knowledge and skills are described in the order of the necessary operations in each paragraph. The included illustrations promote the understanding of the text and add to the contents of the individual sections. In support of the process of learning, questions are included for the trainers to test their knowledge.

Electrical Machines relates to the basic vocational knowledge of electrical machines. Its clear-cut presentation encompasses all necessary knowledge for this field of electrical engineering. Drawing upon only essential natural scientific basic findings, this work features a great many illustrative presentations and commensurate surveys in conjunction with a vividly set out and easily understood text section. Commensurately, the trainees can quickly comprehend the problems in point. Moreover, as the implicit interrelation of theory and practice has been rigorously heeded, this textbook serves the trainees as a working basis in both theoretical and practical vocational training. Tasks and questions for repetition and control feature at the end of each chapter and are geared to essential educational contents whilst, simultaneously, enabling the trainees to test their acquired knowledge.

Electrical Switchgear is based on the fundamentals of low-voltage switchgear. In a didactically edited form it contains the necessary knowledge for this field of electrical engineering. With the help of many figures and corresponding surveys as well as a clear and comprehensible textural representation the trainees are assisted in understanding the problems dealt with* Taking into consideration the unity of theory and practice the trainees can use this textbook as a working basis in theoretical vocational training and in practical vocational training. Taking into account the corresponding IEC recommendations the low-voltage switchgear explained is taken from FRG production, represents a selection and is to be assimilated to products existing in each case.

Electrical Generation In the form of a compendium, it contains the necessary basic knowledge to understand the fundamentals of the of electric current in heavy-current electrical engineering. Related aspects of information electronics are mentioned additionally only wherever it is absolutely necessary for technical reasons. Installation (plant) engineering is only dealt with in the low-voltage range of up to 1 kV. Subjects discussed in great detail in other IBE textbooks, such as “Electrical Installation,” “Electrical Machines” and “Switch-gear”. are only presented in a brief and concise way here. For better understanding of the technical knowledge contained in this textbook, it is necessary to have basic knowledge of natural sciences and electrical engineering. The author tried to explain the subject-matter in a clearly arranged and easy-to-understand manner. Comprehensive illustrations and relevant tables as well as descriptive and comprehensible wording shall help the trainees to conceive the problems dealt with. Considering the inseparability of theory and practice throughout. the textbook can be used by the trainees to acquire knowledge of electrical engineering in the training process, both in theoretical and practical vocational training. Questions for recapitulation and testing, concentrating on the main points of the relevant subjects, shall help the trainees to examine their knowledge.

Lighting Install deals with elementary knowledge in lighting engineering. Starting from a certain scientific knowledge - which is an absolutely necessary precondition - the learning and understanding of the treated problems is facilitated by many illustrations and diagrams as well as comprehensible texts. Thanks to the consistent observance of the unity of theory and practice, the apprentices can use the textbook as a working aid in theoretical and practical training as well. The last part of the textbook consists in tasks and questions for repetition and knowledge tests. They point to the most important contents of training and serve the apprentices for checking their knowledge.
